ANALYSIS OF THE NEAR WAKE PRESSURE IN SUPERSONIC FLOW USING THE MOMENTUM INTEGRAL METHOD.

Abstract

The pressure of two-dimensional base type separated regions is evaluated by use of semi-empirical analysis. The analysis is based on the momentum integral method. Empirical parameters required in the analysis are evaluated from various available experimental data. Good correlation over a large range of variation of the physical parameters is obtained in the cases of two-dimensional supersonic flows for both laminar and turbulent separation over backward facing steps and blunt bases. The axially symmetric base type flows seem to be affected by the inviscid axially symmetric external flow in a different manner than found in the two dimensional case. It seems that the parameters applicable for the two-dimensional base type flows are not sufficient for the correlation of the axially symmetric separated flows. (Author)
